IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Le ttcrs Patent No. 149,920, dated Aprilfll, 1874; application filed March 28, 1874.

the periphery, the two Wheels being containedbetween top and bottom horizontal disks, and

separated, the one from the other, by a flat annular rim a little wider than the depth of the buckets, and fitted at the outer edge with the bottom plate of the scroll-case, to form a joint to confine the water to the upper wheel as it enters from the chutes, and the buckets of the lower wheel being arranged to discharge the water-in the contrary direction to that in whichit is received on the upper buckets, and in a manner to receive the reactionary force, while the upper ones receive its direct action.

By the combination of the two wheels in this manner, an increase of thirty per cent. of power is gained over the power of the lower wheel alone with much less water, as proven by actual test.

Figure 1 is a transverse sectional elevation of the wheel, taken on the line as m of Fig. 2. Fig. 2 is a horizontal section on line 51 y, Fig.

1. Fig. 3 is a section on line 2 z, and Fig. 4 is a section on line a u.

Similar letters of reference indicate correspondlng parts.

A is the upper disk B, the dividing rim C,

the lower disk; E, the upper buckets. The disks are keyed fast to the shaft G, and the dividing rim is fitted at its outer edge with the inner edge of the lower plate H of the chutes, so as to confine the water tothe upper buckets as it enters from the chutes I. Below the'chutes, and in front of the lower buckets, a space, J, is provided by the part Kof the case, for the discharge of the water as it escapes from the wheel. Both the upper and lower buckets take the force of the water mainly at the outer ends, so as to have the best effect on the wheel, the lower issues bein g contracted for that purpose by the thickeued portion L of the buckets. The arrows in Fig. 2 show the direction of the water in the upper wheel, and those in Fig. 3 show the direction in the lower wheel.

It is essential that the upper wheel contain twice the number of buckets that the lower one does, no matterwhat the size of the wheel may be.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The disks A O, rim B, upper buckets E,

lower buckets F, chute-plate H, and case K,

all combined and arranged substantially as specified. 1 A
